Teacher, please tell me how to solve this problem when I open browsersync?

Question

Answer 1

There is a static page under the demo folder. Use the command line tool in the current directory to start browser-sync through:

browser-sync start --server --files "css/*.css"

;

var opn = require("opn");
opn(url, options).catch(function() {
bs.events.emit("browser:error");
});

Source code At: https://github.com/BrowserSyn...

This error will only be reported when there is an error opening the opn library.

"browser:error": function () {
logger.error("Couldn't open browser (if you are using BrowserSync in a headless environment, you might want to set the {cyan:open} option to {cyan: false})");
},

The source code is at: https://github.com/BrowserSyn...

My suggestion is to clean the cache, reinstall dependencies, and upgrade the version.

If the error is reported again, set the open switch of BrowserSync to false and try again.
